Method for non-releasable fixing of one component to a further component

A method for non-releasable fixing of at least one component to a further component, the method comprising:

• introducing a hot rivet into an opening of the at least one component;
• welding an end face of a shank of the hot rivet to a surface of the further component;
• and
• subsequently compressing the shank of the hot rivet, with plastic deformation of the hot rivet, until a head of the hot rivet lies with a pre-stressing force at least in areas on a surface of the at least one component,
• wherein the pre-stressing force, with which the head of the hot rivet lies at least in areas on the surface of the at least one component, is adjusted to a predefined value, which is less than a maximum force, by one of
• adjusting a ratio of an inner diameter of a bearing surface of the head on a surface of the at least one component to a cross-sectional area of the shank;
• providing the shank with first and second length regions that are configured so that only one of the first and second length regions is compressed under plastic deformation;
• providing a thickness reduction in the further component on an area facing away from the shank;
• and
• configuring a lower side of the head in an umbrella shape so that the head is configured to contact the at least one first component only in an outer region.
